Don't even tell me, i paid $4150 for that beast :shock:
So far with the xt i've been most impressed with the big muff, bass overdrive, and bass synths sound (Deeper Underground - Jamiroquai - i'm 90% sure they used the xt). Very usable mod effects (couple of crazy one's you'd probably never touch but hey i'm sure someone will find a use for them), overall very usable unit, some of these things boast tonnes of effects and amp&cab modelling but the majority of them are just crap and unusable in my opinion, the xt (remember, only my opinion) is like having several well configurable effects, a good range, and extreme range of sounds if you like
Like i said, digital isn't my thing, i've heards plenty of phasers but my hacked EH small stone is like liquid, a sheet of silk with necessary imperfections, making it real, the xt has the same liquid quality of a sweet analog effect
But hey, this is my crap rambling, take your rig (YOUR rig - the one which sound you know best) and see how the xt / boss me6b / whatever else sounds - key is have a reference, YOUR RIG!!
That' s enough from me for now, hope this helps! 8)
